both mini and summary only 1 page.
Hey rorr tried your suppliers site but could not access MSDS ended up chasing round in circles
Thanks Anyway

Ateacher asked for MSDS so I thought I would give him latest!
Opened CW Hydrochloric 18 pages tried mini Msds 1 page summary is there something inbetween I can't locate it

Hey Barb
Try looking up Laural Peroxide
Any use of two part epoxies or fibreglass requires ventilation
Have a nice day

Hey Sue
For this I make2 conical flasks / group
1 with air trap delivery tube & 1 with Straight vent tube
half fill both with chicken broth fron supermarket sit both on hotplate and boil, within a week the vented one grows fur, while the air trap remains free of bacteria

Also put in a perforated container of napthalene I had a brilliant display until other bugs got in and ate it and possibly some decomposed

G'Day Carol I have about 500g on the shelf, that has not been used in the 10 years I have been here if you pm'ed me with your address I could post you half

Hi Sue the only thing I can think of is spinach stalk or rhubarb but you could not pick up eiosen stain in rhubarb!
Cheers Graeme

Opps Rubber!

Hi all
I started a thread on this subject!
There is a world shortage of cork due to over harvesting, hence you now get your wine in screw top bottles, Rurrer stoppers at $1 ea approx is very expensive,
Let's get all thoes lateral thinkers out there to come up with an alternative!

Hey Louie! I can lend you a flask and when I worked at TAFE a mob in Newcastle called cryofreeze drove round in little tanker truck and delivered it on site.
Sorry don't know price!
Let me know if you want to borrow flask and I will bring next Friday.

Hey fellas
This is my SS co-ordinator we still make mayo also mix kero / water detergent
Messy does not come near it!

Hey Barb!
Bring that along to the next meeting,I have got to cast an eye over that!

Yeah Robb
Cork stoppers were nice & cheap
Where rubber stoppers are about a $1 each with these exotic compounds are concerned the sky is the limit!
I just threw it in the air to see if some genius could think of a cheap alternative

As you will all realise by now all the cork trees have been over harvested and you can no longer buy cork stoppers!
Rubber stoppers are attacked by a lot of organics even ethanol.
Does anyone have an alternative?

Hi all! been offline for a week but back again.
The answer is ALWAYS clearly label every container. No exceptions!

In the past I have pureed liver and placed in various buffers then put different strength Hydrogen Peroxide on it so they could graph results in a prac exam.
Terribly MESSEY
Does anybody have a better / simpler or other material than liver to do test on?

I would ring up your nearest refinery, for you possibly Shell at grandville and just request it they have to test sample from every load to adjust refinery process they may even send it to your nearest garage with tanker driver.
It is in their best interest to foster up and coming chemists!

I had lousey shelf life with bromine water until I decided to store it in fridge,since then no problems

G'day Robb
I have always used 0.1 M Potassium Iodide Solution.
Have I had it wrong?
or is there a better way?

G'Day Barb Rainbow
Just use 0.1M solutionof potassium hexacyano iron lll
also calledpotassium ferricyanide lll
